Precautions for PC connection to RCON gateway unit grounded at positive terminal of 24 VDC power supply
Intro-14
ME0384-4A
If the gateway unit is grounded at the positive terminal of the 24 VDC power supply, use an
SIO isolator (RCB-ISL-SIO) as shown in the diagram below when connecting a PC to the
SIO connector of the gateway unit.
If a PC is connected to the gateway unit without using an SIO isolator, the power will
short-circuit and cause the PC to malfunction.
Caution
● RS-232 conversion unit (RCB-CV-MW) cannot be used.
